A brief discussion on the problem of not being able to find a file when adding a header file in VS

If a directory or library file name contains Chinese characters or Spaces, enclose them in double quotation marks.

Project, properties, C/C++, attached include directory: fill in multiple semicolon intervals in the directory where the attached header file is located

Project, properties, linker, additional library directory: fill in multiple semicolon intervals in the directory where the additional dependent library is located

Item, property, linker (+ expand before the dot), input, attached dependency: fill in the name of the attached dependency library
